AbstractNinety patients undergoing cardiac surgery were randomly divided into three groups of 30 patients to compare the effects on bleeding and transfusion requirements of either intraoperative infusion of high-dose aprotinin (GpI) or reinfusion of autologous fresh whole blood (GpII) versus a control group (GpIII). Standardized anesthetic, perfusion, and surgical techniques were used. Platelet counts, hemoglobin concentration, hematocrit, fibrinogen, and Ivy-Nelson bleeding times determined at fixed times perioperatively did not differ among the three groups. The total loss from the chest drains was significantly reduced in GpI (328 +/- 28 mL; mean +/- SEM) as compared with the loss in GpII and GpIII (775 +/- 75 mL and 834 +/- 68 mL, respectively). There was a threefold difference in the total hemoglobin loss (GpI, 14.2 +/- 1.7 g; GpII, 50.1 +/- 5.0 g; GpIII, 45.0 +/- 5.2 g). GpI patients also received less banked blood: 250 +/- 53 mL versus 507 +/- 95 mL in GpII and 557 +/- 75 mL in GpIII. No GpI patient required transfusion of platelets or fresh frozen plasma. Fresh whole autologous blood transfusions had no significant hemostatic effect and failed to reduce the homologous blood requirement. Conversely, high-dose aprotinin reduced blood loss and transfusion requirements.
